MonoVista CRS³

(housed, laser class 1, motorized)

The perfect entry into high end Raman and photoluminescence spectroscopy for any type of user.

The MonoVista CRS³ provides a high-end confocal Raman and photoluminescence system of highest performance in terms of throughput and spectral resolution, while maintaining a maximum of convenience to the user.

It also provides optical coupling capability to microscopes, macro chambers, as well as other third-party equipment, like AFM, SEM, Cryostats and other customer desired solutions, provided there is a suitable port for optical coupling via free beam or optical fiber.
